Astronomer Scott Sheppard of the Carnegie institution (USA) with colleagues have discovered two new satellites of Jupiter. This publication reports Popular Mechanics.
Satellites S/2016 J 1 and S/J 1 2017 first discovered in 2016 and 2017, respectively. In diameter they do not exceed two kilometres, like most of the other moons of the planet moves in its orbit against the direction of its own rotation. Both satellites were opened randomly in the search for the hypothetical Planet X.
A complete revolution around the gas giant S/J 1 2016 commits for 1.65 years, eccentricity (parameter of elongation) of the orbit of the moon is equal to 0.14, a celestial body of Jupiter is at an average distance of 20.6 million kilometers. Companion discovered during observations at the Observatory Las Campanas (Chile).
Around Jupiter S/2017 J 1 rotates with a period of 2.01 years, the eccentricity of the orbit of the moon is equal to 0.40, the object is removed from the gas giant at an average distance of 23.5 million miles. The satellite discovered by telescope named Victor Blanco (Chile).
In the period from 2000 to 2003, Jupiter was revealed to 46 satellites. Currently (with S/2016 J 1 and S/2017 J 1) their number reaches 69. The largest planet in the Solar system has, in particular, the largest moon is Ganymede, which amount exceeds the mercury — the smallest planet in the solar system.
